In patients with severe mental disorders, motivation to follow a healthy diet and lifestyle might be low. A diet rich in fruits and vegetables may improve metabolic syndrome, cardiovascular health and mental health. This randomised community-based clinical trial included seventy-four patients with severe mental disorders out of which 37.8% of the participants had schizophrenia or related disorders, 29.7% had bipolar disorder, 25.7% had depressive disorder, 4.1% had a personality disorder, and 2.7% had obsessive-compulsive disorder. The intervention group followed a four-week food education programme (DIETMENT) aimed at promoting fruit and vegetable consumption. A five-month post-intervention analysis showed no increase in participants diagnosed with metabolic syndrome in the intervention group, but an increase in participants diagnosed with metabolic syndrome in the control group. There was a significant reduction in the glomerular filtrate rate in the intervention group. In patients with severe mental disorders, more studies should be conducted to examine the health-promoting effects of adding more fruits and vegetables to the diet. Health professionals can use the results of this study to understand how fruits and vegetables contribute to reducing metabolic syndrome and heart disease risk.
Abstract
OBJECTIVES The aim of this study is to determine the metabolic impact of a nutrition education program on metabolic parameters and the presence of metabolic syndrome (MetS). RESULTS Seventy-four patients were included (mean age, 48.7 years [Standard deviation, SD: 10.8], 55.4% men). The diagnoses of SMD were 37.8% schizophrenia and related disorders; 29.7% bipolar disorder; 25.7% depressive disorder; 4.1% personality disorders; and 2.7% obsessive compulsive disorders. Thirty-seven individuals were distributed in both the intervention group (IG) and the control group (CG). In the IG the presence of MetS was 56.3% and in the CG 46.7%, with no statistically significant difference (p = 0.309). At the end of the study, glomerular filtrate decreased in the IG, body mass index and abdominal perimeter increased in both groups, and there were no changes in metabolic parameters between the groups. Between the baseline and the end of the study, there was no increase in the number of patients diagnosed with MetS (14 at both points); and in the CG the increase was from 8 to 12 (p = 0.005). An intervention based on fruit and vegetable intake could prevent progression to MetS in individuals with SMD, decreasing the likelihood of cardiovascular disease. Trial registration The trial was retrospectively registered on International Standard Randomised Controlled Trial Number (ISRCTN) Register on 11 March 2022 (ISRCTN12024347).

Plain language summary
Chronic psychological stress is increasingly recognized as a significant contributor to mental and physiological disorders in modern societies. The individual response to chronic stressors and resulting disorders depends on numerous factors. The aim of this study was to investigate the cardiometabolic risk profile in participants with ‘high’ and ‘very high’ chronic stress loads and the impact of positive and negative coping factors used. This study is a post hoc analysis of a randomised pilot study. For this analysis, baseline data were available for 62 chronic psychologically stressed participants, of whom 61 participants (43 women and 18 men) were included in the intention-to-treat (ITT) population. Results indicate that: - perceiving high chronic stress is significantly associated with the criteria of the metabolic syndrome. - on the contrary, a very high perceived chronic stress load seemed to be rather associated with mental health risk than with cardiometabolic risk. - inflammation and oxidative stress markers significantly correlated with cardiometabolic risk parameters. - stress load can be coped with in diverse ways and that the coping strategy is crucial for cardiometabolic risk. Authors conclude that long-term studies are necessary to examine further adaptations to chronic stress and to evaluate individual stress-management strategies.
Abstract
Chronic psychological stress can result in physiological and mental health risks via the activation of the hypothalamic-pituitary-adrenal (HPA) axis, sympathoadrenal activity and emotion-focused coping strategies. The impact of different stress loads on cardiometabolic risk is poorly understood. This post hoc analysis of a randomized pilot study was conducted on 61 participants (18-65 years of age) with perceived chronic stress. The Perceived Stress Questionnaire (PSQ30), Psychological Neurological Questionnaire (PNF), anthropometric, clinical and blood parameters were assessed. Subjects were assigned to 'high stress' (HS; PSQ30 score: 0.573 ± 0.057) and 'very high stress' (VHS; PSQ30 score: 0.771 ± 0.069) groups based on the PSQ30. Morning salivary cortisol and CRP were elevated in both groups. Visceral adiposity, elevated blood pressure and metabolic syndrome were significantly more frequent in the HS group vs. the VHS group. The fatty liver index (FLI) was higher (p = 0.045), while the PNF score was lower (p < 0.001) in the HS group. The HS group was comprised of more smokers (p = 0.016). Energy intake and physical activity levels were similar in both groups. Thus, high chronic stress was related to visceral adiposity, FLI, elevated blood pressure and metabolic syndrome in the HS group, while very high chronic stress was associated with psychological-neurological symptoms and a lower cardiometabolic risk in the VHS group, probably due to different coping strategies.

Plain language summary
Weight stigma is a psychosocial consequence in which individuals with obesity experience public discrimination and devaluation. Some individuals apply these negative stereotypes to themselves, which creates a self-directed stigma referred to as weight bias internalization (WBI). While studies have found perceived weight discrimination to be associated with an increased risk of mortality, no study has investigated the relationship between WBI and obesity on the risk of developing metabolic syndrome (MetS). The aim of this study is to examine the relationship between WBI and MetS. The authors hypothesised that among obese individuals, higher levels of WBI would be associated with increased odds of having MetS. Among the 178 obese adults recruited, 159 completed the study. Tests included anthropometric measurements, blood analysis, the Weight Bias Internalization Scale (WBIS) and the Patient Health Questionnaire. This study found that individuals who self-stigmatise may have a heightened risk of dyslipidemia, one component of MetS. Based on these results, the authors conclude that weight stigma is a chronic stressor and may contribute to poor health. Future studies are needed to identify specific pathways in which WBI exacerbates cardiometaoblic risk factors.
Abstract
OBJECTIVE Weight stigma is a chronic stressor that may increase cardiometabolic risk. Some individuals with obesity self-stigmatize (i.e., weight bias internalization, WBI). No study to date has examined whether WBI is associated with metabolic syndrome. METHODS Blood pressure, waist circumference, and fasting glucose, triglycerides, and high-density lipoprotein cholesterol were measured at baseline in 178 adults with obesity enrolled in a weight-loss trial. Medication use for hypertension, dyslipidemia, and prediabetes was included in criteria for metabolic syndrome. One hundred fifty-nine participants (88.1% female, 67.3% black, mean BMI = 41.1 kg/m2 ) completed the Weight Bias Internalization Scale and Patient Health Questionnaire (PHQ-9, to assess depressive symptoms). Odds ratios and partial correlations were calculated adjusting for demographics, BMI, and PHQ-9 scores. RESULTS Fifty-one participants (32.1%) met criteria for metabolic syndrome. Odds of meeting criteria for metabolic syndrome were greater among participants with higher WBI, but not when controlling for all covariates (OR = 1.46, 95% CI = 1.00-2.13, P = 0.052). Higher WBI predicted greater odds of having high triglycerides (OR = 1.88, 95% CI = 1.14-3.09, P = 0.043). Analyzed categorically, high (vs. low) WBI predicted greater odds of metabolic syndrome and high triglycerides (Ps < 0.05). CONCLUSIONS Individuals with obesity who self-stigmatize may have heightened cardiometabolic risk. Biological and behavioral pathways linking WBI and metabolic syndrome require further exploration.
